In this article we are going to discuss power tools. Power tools are basically those tools that work on a motor or electricity. You will also find some tools that work on fuel. There are more than 1000 types of tools that perform various functions and have different calibrations. You will also find cordless or battery power tools that don't need to be plugged into a power source and can work on their in built battery.

OLithium Ion (Li-Ion) - This was the latest battery technology before lithium polymer. They have a higher power density than NiMh and NiCd batteries. Li-Ion batteries generally come standard with most phones. For most people, this battery technology represents the best combination of size, capacity, and value. These types of batteries don't suffer from the poor memory effect and can be recharged anytime.

Why is this important? If you have a relatively new PC the only problem you will get are error messages relating to the clock on start up. No big deal. If your PC is older then a low battery could be a nightmare. I had a PC which once lithium ion stocks every few months refused to boot. Rather than take the PC in for repair or start replacing parts myself the first thing I did was look at the BIOS settings. It was soon obvious that the BIOS settings were corrupt (wrong bus speed). I put a volt meter on the battery and sure enough it was reading 2.2 volts.

The first thing to know is that simple battery care can enhance the performance and useful life of your cell phone battery. Did you know that a cell phone battery should last for up to 400 charge/discharge cycles? That's quite a bit. How does that break down? If you charge your phone each night, your battery will last 12-15 months. If you are only charging twice a week, your battery should last 2-3 years. So, if you can get away with charging less, then that's a sure fire way to getting longer life.

People know that communication is very important and there will be times when the batteries of the cellphones are drained and there are no outlets in sight. At least with cheap cell phone batteries the owner can stock up and put these to their cellphones and make those Lithium battery stocks emergency calls.

ONickel Metal Hydride (NiMh) - Popular battery about 1-2 years ago. They are lighter than Nickel Cadmium batteries, but heavier than Lithium mines Ontario batteries. These should be cycled once in a while for optimum performance.

I could easily have spent a fortune replacing the motherboard, the memory, the processor etc when it all came down to 2 dollar battery. What's more is these batteries are easy to get. What you need is a CR2032 available at most hardware stores like home depot and I've even seen them sold in Safeways. Of course every reputable computer store should stock them. Just check to make sure that your PC uses a CR2032 before you go to the shops!

Recharge the battery to full again and repeat the above steps a few more times. This will allow you to use the battery for a longer time and you can do this no more than once a month. Replacement batteries can be expensive and stretching out their use when you are on a budget can help.
